i recently bought a Lenovo A5500-F 8" tablet and it was working great. But few hours ago i noticed that on one edge of the screen acts a bit weird than the other's if i have the tablet in landscape i have to touch above the home button/back button/recent apps button to actually press it and when i touch those buttons it wont work at all. What i have done is put on the developer tools on the tablet and put show touches so i see whats going on and what i notice is that when i touch the 3 buttons where im supposed to the touch actually appears right on the edge of the screen no where near my finger???
This is not due to system updates since it was doing it before the system updates.
Nothing too major but it gets annoying sometimes when i repeatedly tap the home button .ect nothing works.??
any idea what the problem could be?
